I have Troy Front and rear folding battle sights. They are great sights never have an issue.

To clarify some of the semantic issues, I'm specifically looking at folding sights. My AR does not have a fixed front post which I'm totally fine with. Since the theme of my rifle is largely lightweight, I'll likely go with Magpul sights. I do plan to run some type of optic, likely an Aimpoint of some type.

Keep in mind the weight difference between the Troy rear and the MBUS rear is only like 0.4oz (if I remember correctly).

Troy Tritium folding front and rear. Front is standard AR style and rear is DOA. Love 'em. (Could have saved some coin and gotten the non-trit ones... but... well...)

I personally see no reason for the expense of tritium sights on a fighting long gun. If it is dark enough where you can not see your sight outline, you need a white light for target ID. Once the while light is on, you can see your sight outline.

I've been trying to find a good option to add to my MP15or.. I like the Troys/MI but they're a little expensive.. The MBUS aren't an option (at least the front isn't) due to the railed gas block. Are there any options in between these two?

 

Low profile gas block sights aren't as prolific as the regular height sights. I recommend the MI low profile one - it's not THAT expensive ($80'ish). Or alternately you could get a front gas block riser to raise it to normal height.

SAVE ALL THE OUNCES

On a serious note: Of the sight offerings we're discussing here, how many have the capability to have both peep-hole sizes ready in the folded position?

I think you are over-thinking it at this point.

I could be wrong but I thought the gas block rail was level with the rail on the upper.

nope, I had thought the same thing when I first got into AR's. For example, check out a Stag model 3 (shorter gas block) and a Windham SRC (gas block even with upper) and you'll see the difference. Also keep in mind, if you find a front sight that says its for a gas block, then it is for the shorter gas block, not the one that is level with the upper. In that case you would need a "same plane" front/rear sight combo.

The only reason I ask is because the LWRC sights that I had wanted originally had that capability. Just trying to find the best sight I can.

If you want flip up: Troy if you plan on using it often. Magpul if you want it as a truly "Oh Crap!" backup. Another option that I have tried and liked is the GG&G MAD sight (Which does have the capability of setting either aperture up as the primary)

 

If you want fixed: LaRue or C4 Diopter BUIS.

 

Whatever you choose, avoid ARMS products at all costs.

Sorry I wasn't more specific. I meant that the M&P-15OR has a railed gas block that is on the same plane as the railed upper. Similar to the Windham above.

I love my low profile Troy fixed rear

 

I'll bite, why avoid ARMS products?

GG&G MAD because it was on the rifle when I bought it, and it does have an NSN, which has to account for something.

I know the arms #

I know the arms #41 71 has a problem where when you hit the button to flip up the small aperture is carried forward from its standard position. This is a major pain in the ass if you're using it in a true emergency situation where you have to take your hand out of position flip back the aperture and reset your firing position.

 

Edited

I used a fixed front iron sight and troy DOA rear folding sight.... fixed front sight never bothered me.. and as pointed out it is less to do if the optic fails.. fold down rear to stay out of the way when using the optic.. Troy because they are reliable and sturdy...

 

I use this. Exactly same reasoning.

A.R.M.S. Mounts: helping terrorists walk away unscathed since 1980!

 

Seriously, If you find A.R.M.S. is the answer, ask a different question. Their mounts are weak/soft and do not hold zero well. They break often under normal use and are hated by most of the guys out there that are forced to rely on ARMS gear.

 

Not to mention the fact that, IMO, Dick Swan's business practices leave a lot to be desired.

I have all troys but recently bought some of the poly ARMS with metal inserts and really like them. Still, nothing imho comes close to the Troys as they are well tested, built like tanks and you can drop them from shoulder height and they won't lose their sighting.

i believe that right now, although it seems like i change my mind every day, that on my new build i will be going with a yankee hill railed gas block (low, height NOT to match upper) and troy folding sights, front gas-block height and rear..well, standard height.  i like the idea of fold-down sights that tuck below optics and get out of the way while being transported, plus i was never a huge fan of the fixed "triangle" F type front sight base - just looks dated although i understand the functionality.

 

troys are pricey, maybe...but you get what you pay for, correct?  people seems to complain that midwest industries sights, especially their rears...loosen up with little firing.  so for a little more dough, i think the troys are the way to go.  i've shot other ARs with them and well...they work, i'm not sure how much you can ask from buis other than they stay true and don't fall off under fire.

So despite having asked this question over a year ago, I figured I'd update. Finally purchased a set of LWRC Skirmish sights and I'm quite happy with them. I'll post pictures within a day or two. Really solid and much better sight picture than the MBUS sights they replaced.

I will speak hearsay, as I don't know if this is true or not. I asked a friend who likes magpul, and is far more experienced than myself about the plastic magpul BUIS because I saw them on sale. He said that in his experience, they don't hold a zero, and that it's best to go with Magpul's metal BUIS.

I trust his opinion, but your mileage may vary.

Oh, and if it makes any difference, when I got some HK style sights, he was critical of that decision. So I have no clue haha.

I have had no issue with either of my rear magpul mbus. I have an HK style from sight on one of mine but I prefer my a2 fsb

Flip ups >>> Troy

Fixed >> Daniel Defense

I got the psa metal ones..they came with my aimpoint.

Fixed: DD

Flip: MBUS Pro (holy small footprint, Batman!)

This is what I used with a fixed front A2 sight

I'm a fan if the MBUS and I use them.

All of the ones mentioned in the thread are solid options and all can be prone to failure if dropped.

Andrew of Vuurwapen Blog did a review of popular BUIS after a drop test directly onto the sight when mounted. http://kitup.military.com/2012/07/back-up-iron-sight-drop-test.html

 

It all ends with what you prefer the look and price of when we are talking about first rate manufacturers.
